OSHA’s Environmental Health & Safety requirements can be extremely costly to implement, but there are ways to save thousands of dollars on at least parts of the requirements. If you are an employer who is required to implement an employee emergency evacuation system, also known as an employee alarm system, to satisfy one of OSHA’s standards, this article will help you do that.

The purpose of OSHA’s Emergency Evacuation Systems standard 29 CFR 1910.165 is to provide an early warning system for implementing emergency action and to give employees time to safely escape a building or area in the event of an emergency situation.

Wireless Emergency Evacuation System

Below are some examples of instances that require an emergency evacuation system, including links to OSHA’s website for more information.

What is an emergency evacuation system? According to OSHA, “An employee alarm system can be any piece of equipment and/or device designed to inform employees that an emergency exists or to signal the presence of a hazard requiring urgent attention. National Fire Protection Association (NFPA) 72, National Fire Alarm Code, requires a fire alarm signal to be distinctive in sound from other signals and can not be used for any other purpose.”

The OSHA Standard goes on to say that you can use audible alarms that “include bells, horns, sirens, voice announcement systems, and other devices that can be distinguished above and apart from the normal sound level within the workplace.” They say the most effective means are voice signals or an interrupted steady sound (off and on sound).

One of OSHA’s recommendations is a “Workplace Announcement System.” Here’s how they define that: “Speakers can be used to play a live or recorded voice message. They are often ideally suited for large workplaces where phased or guided evacuations are needed.”

In businesses that have large buildings or cover a lot of ground, installing a wired emergency evacuation system can cost tens of thousands of dollars. What you will learn here is how to do it for a fraction of the normal cost.

The heart of this system is a Wireless PA System. A wireless PA system consists of a wireless receiver box connected to a horn PA speaker via a cable, and then some sort of wireless transmitting device, which could be a two-way radio or base-station intercom.

Someone who wants to make a page to the Wireless PA system just has to set the transmitter to the same channel as the wireless PA and then press the push-to-talk button on the transmitter.

The system has a range of up to a mile or more and the range can even be extended by adding an external antenna to either the Wireless PA, the transmitter, or both. If you have a wired PA system already, you can also get a Wireless PA System Interface device that will receive transmissions from radios and then broadcast those transmissions over your wired PA system.

There are several devices that can communicate with the Wireless PA system. The indoor or outdoor Customer Service Call Box is one of them. It can be used as a panic button that when pressed sends a recorded message to two-way radios, base-station intercoms, or to a wireless or wired public address system.

You can record whatever message you want, or you could simply record a siren sound that plays when the button is pressed. If you have multiple areas where you need a panic button, then you’ll want to make sure you can distinguish between the recordings so you know where to send help.There are other devices you can add to your system such as Wireless Call Boxes if you have locations outside that need to broadcast emergency messages from a fixed location.

A wireless call box is essentially a two-way radio in a heavy duty water-resistant housing. When its button is pressed, the person pressing the button can talk to other hand-held radios, base station intercoms, and even the Wireless PA system.

There are some situations where placing a phone call to notify an emergency response team is just not fast or reliable enough. With a wireless call box, a simple press of a button notifies everyone that needs to know. Probably the best way of using it would be to have it contact emergency personnel who then make pages over the employee alarm system.

Keeping your employees safe in any way you can should be a top priority of yours. Using all of these devices as an employee alarm system is one way to do that, while saving thousands of dollars over the cost of a wired system.

Many retail stores and businesses cannot afford to have a full-time person manning the front door to greet customers. Business owners and employees could be roaming the building or buildings, or even the grounds around the building where customers arrive. Such is the case with landscape nursery operators, funeral home operators, used car lots, or hundreds of other types of businesses.

What they need is a way to monitor the front door from a remote location. They need the ability to be mobile and still know someone has arrived. That’s where a wireless alert system comes into play.

A wireless alert system consists of a battery-powered, wireless motion detector installed by the front door, and fixed base station intercoms. mobile handheld intercoms, or both to receive notice that someone has arrived at the front door. When a customer arrives, the motion detector will send a verbal “Alert zone 1” message to let monitoring personnel know someone has arrived at the front door.

If you have multiple entry doors, you can set up four motion detectors and each door will have it’s own alert message so you’ll know which door the customer came in.

Not only can you use this system to monitor the front door, but it can be used for communication between employees. The handheld radios and base station intercoms can be used to talk between units.

This system has a range of up to four miles so you should be able to cover your entire business with communications and alert messages.

The system also works as a security system at night so if you or someone is within range of the motion detectors, they will get the message.

The system is not only cost effective, but can be easily installed in a matter of minutes.
